I enjoyed staying at Evan's apartment. It looked just like in the photos - spacious, clean and equipped with A/C to escape the Bangkok heat. I booked the room on the roof (if you have issues climbing 4 or 5 short flight of stairs, you should opt for a room on a lower floor - I appreciated the exercise though!) which had a hang out spot right beside it. Evan was very approachable and friendly, and he (and his three gorgeous dog) was present to personally welcome me. And of course, the location of this apartment is great - just a couple of minutes on scooter/motorbike from Lumphini train station (this makes going anywhere in Bangkok so convenient) if you ride pillion with the orange-vested riders for 20-30 baht. Else, it's just a 10-15 minute walk in. If you have the time, I highly encourage heading to the Lumphini for a morning stroll.
TL;DR - I definitely recommend staying at Evan's!
